100% on my 128GB iPhone SE but then it was a sealed brand new device.

However my older SE that it replaced was on 93% after two years and still performing great, I just wanted more storage.

Still 100% battery on iPhone 8 64GB (5 months old, bought mid August 2019).

To try to maintain good battery health I usually keep the charge 25-75% and stop charging if the phone gets noticeably warm.

The '8 battery is small and I was surprised to recently get over 5 days from a full charge, with minimal usage (typically 1 short call, a dozen text messages, and a few minutes Safari per day). Many phone settings have been tweaked for best battery life.
5 days of standby is good, but as far as iOS is concerned, it’s neither exceptional nor rare. iOS’ standby time has always been impressive.

I have an iPhone 5c and it has been 15 days on standby with 40 mins of combined usage and it had 50%.

As per battery health, I charge it whenever I like, but always with the slowest charger available. (In this case, the 5w one). I don’t use a fast charger and I don’t charge my phone with the iPad brick - even though it’s faster.
I also don’t update iOS, so the battery life is better than if I were to update.

I would have thought you would see software improvements to battery life if you update iOS?

Launch day XS Max, still at 97% apparently but I’m sceptical and expecting that to suddenly drop in the near future.

iPhone XS Max. 93%. I'll get a new battery when the new phones come out this fall and use it for 2 more years. That seems to be my schedule nowadays.

iOS updates absolutely destroy battery life, on every iOS device currently in existence. People are VERY quick to blame battery health and other largely irrelevant factors, but the issue is that iOS updates will cripple the battery life.
Every single device has gone through the same, starting two major updates in (if the original is iOS 9, then starting from iOS 11, battery life will be horrible, and it will keep getting worse).
Want good battery life for years on end? Don’t update.

Huh? That’s one of the most absurd things I have read on here. What proof do you have? Updating does nothing to effect your long term battery life. The only things that effect battery life is charging habits and how much and how you use the phone. Per your idea any software changes you would have to never add an App or update those also.

You are mistaking battery life with battery health. Battery health impacts the other mildly or a lot (depending on... the iOS version), and battery health itself is affected by what you said, among other factors (heat is a prominent one)
Battery life depends on a lot of factors, most importantly, how you use your phone, and the iOS version.

The one I referenced is battery life (i.e, how many hours of screen time and/or usage you get per charge), not battery health (battery capacity compared to when it was new, generally measured in mAh).

Seeing as most of us are getting brand new shiny phones tomorrow. I figured it would be neat to compare everyone’s battery health in the device that’s getting replaced. So What is everyone’s current battery health? As in maximum capacity percentage found in settings.

Just list your current iPhone type, how long you’ve had it and your Maximum Battery Percentage.

I’ll start.

iPhone 10s Max
Age: 1 year(preordered at launch last year)
Maximum Battery Percentage: 91%
Just got mine replaced under AppleCare warranty for a hardware issue. So current is 100%. Wonder now about the “old” iPhone’s battery capacity... Used it for a little under 1.5 years.

I’m down to 95 percent on my 11 PM. I do use my phone a lot and game, etc, so probably lots of charging cycles and heat. The thing is I’m positive by battery life
isn’t only 5% less - it’s substantially less than new. Also seems to be charging slower as well.

I had an iPhone 6S for 3 years without replacing the battery and noticed that the indicator dropped to 86% after 1.5 years and was at 84% when I replaced it. Even tho battery dropped significantly and needed to be charged every few hours with very light usage.
The coconut battery Mac app showed 34% which was more accurate.
So from my personal experience: the iOS indicator is not very accurate it is best used in conjunction with coconut battery, it sticks at 80% probably because Apple does not want to give out free batteries.

About 15 months in on my XS, battery is at 92% which seems pretty decent to me. Sits in a wireless charging dock for about 6 hours each night and whenever I am at home during weekends. 8% in 15 months, I'll take it.

87% on a 2 year old 6s. Day to day experience suggests it isn't lasting the time you'd expect with 87% of what it was originally rated for remaining. I blame newer OS and apps using more power. The original estimates for the 6s were based on running iOS 9–the OS it came with.

People need to remember that the lifespan of a lithium ion is from 100% to 80%. When it says you have 80% health, that battery is at the end of its life. To put it another way, once you see 90% health just pretend it says 50% because that is basically the halfway point for the batteries useful life.

Not that great anymore. I'm down to 86% after 13 months with my current 8 Plus.
Lol same here. 12 months now and at 88% :( I still love the phone though. Just gotta keep an eye on the battery when I get halfway through the day to see if I should top up or not

I went on vacation to a place with a very hot climate in late summer and my health went from 96% to 92% in only 3 weeks. So it definitely took a hit.

Yeah, i may have to replace it soon before the battery loses even more health, to the point where i would have to charge it multiple times a day.
